Application filed PebruaryZ i, 1890. Serial No. 341,607. (No model.)

To aZZ whom itmay concern.-

.Be it known that I, ISAAC S. MCGIEHAN, of the city, county, and State of New York, have invented a new and useful Improvement in Railway-Rail Joints, of which the following is a specification. Thisinvention relates to railway-rail joints, its object being to provide a foundation under the bottom of the rail ends where they areo1ned together and to hold the. rail ends rig- 1d1y upon the foundation without drilling or cutting the rail and so that there is no possibil ty of the rail ends moving independent of the foundation which they rest upon, as

will be hereinafter explained.

- In the accompanying drawings, which form a part of this specification, my invention is fully illustrated, with 'similarletters of refer To const-ruct my improved bridge-joint, I'

take a piece of channel-beam iron, as shown in cross-section at A, Fig. 1, the requisite size and cut the ends of its sides out, as shown at I c 0; Figs. 2 and 3, so that it will rest upon two the rail-base.

cross-ties, oneend on each tie, as shown in Figs. 2 and 3, with the sides of the channel extending downward between the ties to form a truss and at the same time providing a fiat upper surface for the rail ends to restupon. I then provide two clamps, as E E, Figs: 1 and 3, formed, as shown in cross-section in Fig. 1, with two jaws, one running along its top edge and the other running along its'lower edge,

as shown at .m and n, Fig. 1. The jaw n fits under and engages with the lower side of the channel-bridge A, and the jaw m passes over the bolts d through the clamps and sides of the channel-beam bridge, and when these are drawn together the jaws mslide up on the rail-base until the rail is finally seated 'upon the channel-beam bridge, and by utilizing the channel-beam bridge a piece of chemically- I proach'in'g side. Thus the rail ends are thrown After these are in place, I pass bevel of the rail-base as a wedge for the jaws m to slide over, together with the bolts d, sufficient clamping force is obtained to practically convert the whole into a solid structure, so that the joint is quite as strong as any other part of the rail. Before putting my joint'toget-her, however, I place on top of the prepared or tax paper, as 3, Figs. 2 and 3, which acts as a cushion for the rail to rest upon and destroys the metal contact between the rails and the bridge, and it also prevents the parts from rusting together. v

' When a locomotive is approaching a joint in the track, the rail always deflects on the 0pposite side of the tie from the joint on the apupward, which is proven from the fact that fish-plates or splice-bars always crack and begin-to-break on the top side first. Thus it is just as important to hold the rail ends down andkeep them from going up as it is to hold them from going down under the weight of of the locomotive, and this is the particular feature which I claim for my invention. The method of fastening the-parts togetheris such and so powerful that each and every part combines to form one very rigid structure, which'holds the rail in perfect line and prevents either an upward or downward movement of the rail ends. r

I desire more particularly to call attention to the fact that the lower jaws n of the clamps E do not slide under the bridge when thebolt is tightened, as is-usual with such joints. The

lowcrfj aw n is provided with a shoulder, which strikes the outside of the bridge and prevents it from sliding farther under, thus throwing is shaped so as to utilize the bevel of the railbase to slide over, and thereby produce a more substantial and rigid grip than couldbe otherwise obtained. I

In order to prevent the rails from creeping, I provide, when necessary, four depressions in the corners or edges of; the channel-beam bridge A, as shown at 0 0, Fig. 2, and bend the edge of the flange of thc rail down to fit into these depressions, so that when the clamps E are in position it would be impossible for I the ends of the rail to drawout.

" The form of the channel-beam bridge may 9 the entire movement to the upper jaw,'which drawn together to create a clamping-power to combine the bridge and-rails together.

Having thus described my invention, what I claim therefor, and desire to secure by- Let-' ters Patent of the United States, is v 1. A 'railway-rail joint consisting of the bridge or foundation piece A, of any desireable form, the clamps E E, provided with the jaw'n, fulcrumed against the bridge or foundation piece A at the lower edge, and the jaws 'm, formed to slide over the rail-base when the two are drawn together as described, in combination with suitable bolts d, substantially as set forth.

2. In a rail-joint, the combination of'the bridge or foundation piece A, provided with the extending ends 0 c, which restupon the ties B, the clamps E, providedwith the jaws m and n, the jawn of which is fulcrumed against the lower edge of the bridge or foundation piece A, and the jaw 071 formed to slide over the rail-base,as described, in combination with the intermediate chemically-treated paper, and the clamping-bolts d, substantially as specified. r

3. A bridge. or foundation piece, as A, provided with the depressions 0, the rail 6, having its base-flange bent down to engage with the said depressions, in combination with suitable clamps and bolts for holding the rail and foundation-piece together, substantially as described.

In testimony that I claim the foregoingimprovement in railway-rail joints, as above described, I have hereunto set my hand this 21st day of February, 1890.
